Well, she might be very protective. Since Joker is often in chaotic and dangerous situations, she could be constantly worried about his well - being and try to shield him from harm in the fanfiction world.
She could be a complex character. Maybe she has her own dark past that influences how she raises Joker. For example, if she had a difficult childhood herself, it might make her either over - indulgent or overly strict with Joker. In the fanfiction, she might also have some unique skills or knowledge that she passes on to Joker, like a special way of thinking or a particular skill in surviving in Gotham's underworld.
Her presence can introduce a whole new layer of backstory. For instance, if the fanfiction focuses on Joker's origin, Bella's relationship with him can be a key factor in shaping who he becomes. It could be that her actions or inactions lead to his transformation into the Joker.
One common theme is the clash of different worlds. Bella comes from a more supernatural - tinged world in Twilight, and the Joker is from the gritty, crime - filled Gotham. So, the fanfictions often explore how these two disparate worlds collide when the characters meet.
One common theme is the idea of opposites attracting. Bella and Joker are very different characters, so this theme of how their differences complement each other is often explored.
There's a fanfiction titled 'Bella and the Joker's Unlikely Alliance'. In this story, Bella's unique personality somehow catches the Joker's attention, and they end up in a strange alliance. It delves deep into their complex relationship, showing how two very different characters can be drawn together. The author does a great job of creating a believable scenario where they have to rely on each other in a rather chaotic world they find themselves in.
There's also a possibility that some of the more morally grey characters in Gotham, like Catwoman, could be Bella's allies. Catwoman has her own code of ethics, and she might relate to Bella's struggle between good and evil. They could work together in certain situations, especially if there are mutual benefits involved.
In this fanfiction, Bella's vampiric allure might attract the Joker in a different way than he's used to. He could start to see her as a new kind of plaything. Bella, however, might see the Joker as a way to break free from the monotony of her vampire existence. Their interactions would be filled with tension, as Bella tries to keep her vampire identity a secret while the Joker is constantly probing for more information about her.
Well, it could be about Bella trying to break free from her father's, the Joker's, evil influence. Maybe she has a good heart in contrast to him and wants to use her skills for good, like helping Gotham in a more positive way.
One popular 'bella is mother nature fanfiction' might be the one where Bella uses her newfound powers as Mother Nature to heal a dying forest. The story could be about how she connects with the plants and animals on a deeper level.
Well, without reading it specifically, it could be about Bella taking on a motherly role within a pack. Maybe she's protecting the pack members, making decisions for the good of the group, or having some sort of special bond with each of them.
One key element is the clash of different universes. Bella Swan comes from the relatively normal (compared to the Suicide Squad's world) world of Twilight. So, when she's thrown into the Suicide Squad's world led by the Joker, there's a big contrast in values, powers, and the general way of life. Another element is the relationship between Bella and the Joker. It could be a relationship of enmity, where the Joker sees Bella as a new plaything or an ally in some strange plan he has. Or it could be a more complex relationship where Bella tries to understand the Joker's madness and maybe even reform him. Also, the action and adventure elements are important. The Suicide Squad is known for its dangerous missions, and Bella getting involved in those adds a lot of excitement to the fanfiction.
